First 8K UHD signal generator for satellite TV tuners shown at Inter BEE 2017

SiTune Corporation has successfully tested its tuners for 8K Ultra High Definition satellite TV in line with the ISDB-S3 standar being rolled out by Japan’s public broadcaster NHK in 2018, in preparation for the Olympics Games 2020 in Tokyo.

SiTune tested tuners for 8K Ultra High Definition satellite TV in line with the ISDB-S3 standard to be rolled out by Japan public broadcaster NHK in 2018 ready for the Olympics Games 2020 in Tokyo.

The R&S SLG satellite load generator from Rohde & Schwarz generated the ISDB-S3 signals. The tuner was shown on the SiTune booth (3302) at the Inter BEE 2017 trade fair in Japan.

In 2018, public broadcaster NHK will roll out the ISDB-S3 8K UHD standard. SiTune already introduced the world's first ISDB-S3 tuner in January 2016. By the second quarter of 2018, the manufacturer will start mass production of the tuner, which supports satellite, terrestrial and cable reception.

Interoperability test

In the interoperability test, the SiTune STN6528 tuner successfully received and demodulated the ISDB-S3 signal. The SiTune STN6528 tuner was operated as a plug-in board on an SC1501 demodulator evaluation board from Socionext.

The R&S SLG simultaneously generates up to 32 satellite transponders in realtime. This extremely compact 1 HU, 19" unit replaces a full rack of many separate signal generators. Users save energy and space, and eliminate the time-consuming, error-prone operation of multiple instruments as well as the cost of servicing and calibrating them.

Choice of transmission standards

The R&S SLG can be operated in the 250 MHz to 3225 MHz frequency range with a modulation bandwidth of 500 MHz. Customers have a choice of transmission standards, including DVB-S, DSNG, DVB-S2, DVB-S2 wideband, DVB-S2X (also with channel bonding), ISDB-S and ISDB-S3.

Several R&S SLG generators can be cascaded to generate signals for the entire satellite IF band. In multicarrier operation, the R&S SLG generates up to 32 transponder signals and transmits the content of transport streams that are fed into the instrument via an ASI, Gigabit Ethernet or optical SFP+ interface via IP.
